-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Frederik:
That's an interesting question. Thank you. - From independence until early 80's Tanzania had a first road classification system that, although not the official system anymore, it seems to be present in many road maps up to now. Then, they changed to a British-like A-B system (AXXX for trunk roads and BXXX for lesser roads). That system was changed to the current official system in 2000, with TXX for trunk roads (T1 to T25) and R for regional roads. I have written a hackpad where I am gathering all this info [1]. All TXX roads are already mapped in OSM, but some might be wrong, according to the difference in km with the wikipedia (German and Dutch) references (see hackpad). Moreover, all of them are mapped as a mix of trunk and primary, many of them primary for some segments and trunk for others. So this is something that has to be corrected too. Finally, there isn't any route relation for any of these roads: another TODO task. It's true that there isn't any explicit reference about this in the imports wiki, but we warn about not changing the OSM tags in the workflow wiki [2]: "We will keep the highway=* tag of the OSM way (in this example: highway=tertiary), unless we really think it is wrong according to the Highway Tag Africa wiki. But in any case we will never keep highway=road." I will add something about this to the import wiki, and make it more explicit not to change ref=* tags in the workflow wiki too. Correcting/adding ref tags to the Tanzanian roads is out of the scope of this import. It can be done at any time, but a good thing would be to do it right after the import is done, or even better right after each Tasking Manager job are being finished. In any case, this would have to be discussed with the Tanzanian local OSM community, at least about what the tagging for the T and R roads should be. This import won't change anything about that, so we can consider that this is an issue that doesn't affect this import. Cheers, Rafael.
